  • Cervical thymus functionally mimics the thoracic thymus in supporting T cell development and exists in a subset of mice and humans. Importantly, it remains unknown whether the cervical thymus generates an overall repertoire of T cells that are self-tolerant similar to the thoracic thymus. Mice that developed T cells in the absence of the T cell output from the thoracic thymus developed a disease characterized by lethargy, swollen eyes and cachexia. Our data supports that the cervical thymus can function in the absence of the thoracic thymus; however, the T cell repertoire is not fully self-tolerant. Evidence suggests that disease occurs as a result of lymphopenia-driven autoimmunity similar to disease seen after transfer of thymocytes into lymphopenic hosts. Therefore, we used this model to demonstrate that IL-7, an important homeostatic cytokine, can augment disease although the mechanism remains to be elucidated.
